INCINERATOR Filed April 17, 1930 2 SheetsSheet 1 Earl amwwboz JfifBean a Patented Mar. 31, 1931 UNITED STATES- JAMES A. BEAN, or wmoiva'iumnnso'ra INGINERATOR- Application filed April 17,

T he invention aims primarily to provide a new and advantageous incinerator in which the products of combustion from a furnace or the like are used to dry the refuse to be burned.

Another object is the provision of an incinerator in which all heat generated by burning of the refuse is utilized instead of going to waste.

Vith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings. 7

Fig. 1 is a front elevation partly in section showing the incinerator operatively connected with a furnace.

Fig. 2 is a horizontal sectional view on line- 22 of Fig. 1.

Fig. 3 is a vertical sectional view of the incinerator.

Fig. 4 is a detail vertical section showing a modified construction.

In the drawings above briefly described, the preferred construction has been illustrated, and while this construction will be herein specifically explained, it is to be understood that within the scope of the invention as claimed, variations may be made.

The numeral 5 denotes a vertically disposed cylindrical casing closed at both of its ends and provided near its lower end with a grate 6 to support the refuse to be burned. Above the grate 6, the casing 5 is provided with a refuse door 7 and below said grate, an. ash door 8 is provided, these doors being mounted at the outer ends of throats such as 9. At the upper portion of the casing 5, Pprovide inlet and outlet sleeves 10 and 11, for products of combustion, said sleeves being secured to said casing and projecting outwardly therefrom, the outer extremities of said sleeves constituting collars for engagement with pipes. A pipe 12 is shown engaged with the sleeve 10 and connected with the outlet 13 for the products of combustion from a furnace 14. Another pipe 15 is shown engaged with the sleeve 11, and said pipe 15 leads to the chimney or stack. Between the sleeves 10 and 11, the upper portion of the casing 5 is provided 1930. Serial No. 445,102.

with a vertical bafiie which may either be a The baflie 16 or 17 extends downwardly from the top of the casing 5 and extends across the interior of this casing between the sleeves 10 and 11, so that all products of combustion entering casing 5 through sleeve 10, will be directed downwardly onto the refuse upon the grate 6, effectively drying the same and preparing it for combustion. If sparksor flame do not enter the casing 5, and'ignite the refuse, it may be ignited in any other desired. way and as it is consumed, all gases pass off through the sleeve 11 with the products of combustion from the furnace.

In order to utilize the heat generated by burning of the refuse, I provide an air-heating acket 19 around the casing 5, said jacket being provided with an air inlet 20 and with any desired numberof hot air outlets 21 which may lead to registers or the like (not shown). The sleeves 10 and 11 extend through the jacket 19 and project therefrom sufficiently to provide collars for engagement with the pipes 12 and 15 and the door threats such as 9, extend also through said jacket, being provided at their outer ends with suitable frames 22 upon which the doors 7 and 8 are mounted.

By providing the novel crn'istruction shown and described or a substantial equi lent thereof, an incinerator is provided in which the products of combustion from a furnace or the like, are used to thoroughly dry the refuse preparatory to burning, and in which the heat generator by incineration, is utilized instead of going to waste. The details disclosed may be followed if desired, but Within the scope of the invention as claimed, numerous variations may be made.

I claim 1. In combination with an outlet pipe for the products of combustion from a furnace;

an incinerating casing into which said pipe discharges, said casing having means for directing the products of combustion against the refuse and being itself provided with an outlet pipe for products of combustion; an air-heating jacket around said incinerating *asing, an air inlet into the space between said jacket and casing, and a hot air outlet pipe leading from said space.

2. An incinerator comprising a vertically elongated incinerating casing, an air-heating, jacket surrounding said casing and having an inlet and an outlet, a refuse door throat and an ash door throat extending from said casing through said jacket, doors for said throats, a refuse grate across said casing between said throats, inlet and outlet sleeves for products of combustion, said sleeves being secured to and connnuni(rating with the upper portion 01 said casing and projecting outwardly through said jacket for connection with pipes, and a vertical baflie extending downwardly from the top of the casing, said baiiie terminating above said grate and extending across said casing between said sleeves.

3. An incinerator comprising a vertically elongated casing having a refuse grate near its lower end a refuse door above said grate and an ash door below said grate, a fiXQdlV mounted vertical baffle projecting downwardly from the upper end of said casing and extending across the interior of the latter, said baffle terminating above said grate, an inlet for products of combustion from a furnace, said inlet opening into the upper portion of said casing at one side of said bafiie, and an outlet for products of combustion leading from the casing at the opposite side of said baflie.

I11 testimony whereof I affix my signature.
